Tessellations has consulted on several projects to manage GIS data assets in the ArcSDE environment.  Worked with migrating from SDE 8.3 to 9.1 which involved working with users to determine which layers needs to be migrated.  Process documents were created for every single layer in SDE (approximately 1500).  Metadata standards were created and tools were developed that would ease data entry and help in maintenance activities.  Another similar project was done where the Client acquired two companies and the SDE environments have to be merged.  This integration project also involved a layer by layer evaluation of two SDE environments.  Worked with programmers to make sure automated processes that moved data from a master database into the SDE we migrated and tested in the new environment.
